In general（一般地）people talk about two groups of colours：warm colours and cool colours.
The warm colours are red，orange and yellow. Where there are warm colours and a lot of light，people are usually more active（积极的）.People think that other colours，red，for example，are exciting. The cool colours are green，blue and violet（紫色的）.These colours are relaxing. Where there are cool colours，people are usually quieter. People who like to spend time alone prefer blue.
One scientist says that time seems to pass more slowly in a room with warm colours than in a room with cool colours. He suggests（建议） that warm colours are good for living rooms or restaurants. Cool colours are better for offices and factories，for the people who are working there want time to pass quickly.
Scientists do not know why people think some colours are warm and others are cool. However，almost everyone agrees that red，orange and yellow are warm and that green，blue and violet are cool. Perhaps warm colours remind（使想起） people of warm days and cool colours remind them of cool days. Maybe it's because in the north the sun is low during winter，the sunlight appears quite blue，and the sun is higher during summer and the hot summer sunlight appears yellow.
